Hello,

Does anyone know of a Open Source Desktop GIS application that can be
extensible programmatically (possible using C++)?

I'm currently using ESRI ArcGIS, and I code plugins using C#.
I'm looking for a replacement to be Open Source, cross-platform (Windows,
Linux, MacOSX), more efficient than ArcGIS and I would like to write
plugins using C++ (If possible avoid COM )

Thank you very much and regards,
Fernando Pelliccioni.
